How to Estimate Delivered Lumens in
Emergency Mode
Use the formula below to estimate the delivered
lumens in emergency mode
Delivered Lumens = 1.25 x P x LPW
P = Ouput power of emergency driver. P = 10W for
E10WLCP option.
LPW = Lumen per watt rating of the luminaire. This
information is available on the ABL luminaire spec
sheet. LPW = Lumen per watt rating of the luminaire.
LPW information available in Performance Data
section.
